Text-To-Speech software synthesizes text strings and files into spoken audio using synthetic voices. Where can I get SAPI 4?

Also, you may download and install the Microsoft; the Speech Control Panel will add an icon to your Control Panel to enable you to list the compatible text-to-speech engines installed on your system and customize their settings for your use.

Where can I get SAPI 5? Windows XP (and later versions) comes with SAPI 5.

Speech Engines How do I know what Text-To-Speech voices have been installed on the computer? You can view all the voices available on the computer by following Control Panel -> Speech -> Speech Properties -> Text To Speech -> Voice selection. Windows 10 has the new voices Microsoft Mark Mobile and Microsoft Zira Mobile, but they are not available in text-to-speech software. Is it possible to unlock the new voices? By default, the Microsoft mobile voice is locked for using in text-to-speech software via SAPI 5. You can unlock it with a simple registry tweak. Download the, extract the file for your language and for your version of the operating system ('mobile_x86.reg' for 32-bit and 'mobile_x64.reg' for 64-bit), click the right mouse button on the file's name and choose the context menu item 'Merge'.

The Microsoft mobile voice will appear in the list of the available voices in Balabolka. My computer is running the 64-bit version of Windows. I have installed the 64-bit Runtime package for and the English voices. But the list of available voices is still empty. Where is a problem? Balabolka is the 32-bit application. You need to install the 32-bit Runtime package for Microsoft Speech Platform also.

What is Google Text-To-Speech? In Google Translate you can find a 'Listen' button that converts text to speech. After pressing of this button a browser starts to download MP3 file. The service supports converting to speech texts not longer than 100 symbols. Balabolka allows to divide big text on small parts, create an audio file for each part and merge them together (WAV, MP3 and OGG formats are supported). SAPI Tags How do I change a voice during reading aloud?

Use the XML tags. It is recommended to write the opening and closing tags inside the same paragraph. For example: Hello, how are you? I'm getting the error message ' OLE error 80045042'. What does that mean?

This error means: 'The XML parser failed due to bad syntax.' You must verify the syntax of the XML tags inside the text. Or, some part of the text looks like the start of an XML tag, and it is confusing SAPI. If you don't want to use XML tags, remove the symbols ' ' from the text (or replace them by words 'less than' and 'greater than'). Software Usage I open a DjVu file, but the program doesn't show any text. What is wrong?

DjVu format was designed to store scanned documents. A DjVu file contains images of pages for books, magazines, etc.

Also, DjVu can contain an OCR text layer. Balabolka can extract data from a text layer of DjVu only. If such layer is not available, the only way to get text is to use a text recognition system (for example, FineReader).

How can I remove dashes in the beginning of paragraphs? You should use the main menu item 'Edit Replace'. Type ^p— in the Find what box and ^p in the Replace with box.

The program allows to use most of special codes from Microsoft Word: ^p Paragraph mark ^t Tab character ^ nnn ASCII character (where nnn is the character code) ^0 nnn ANSI character (where 0 is zero and nnn is the character code) ^U nnnnn Unicode character (where nnnnn is the character code) ^+ Em dash ( — ) ^= En dash ( – ) ^^ Caret character ^s Nonbreaking space ^? Any character ( in the Find what box only) ^# Any digit ( in the Find what box only) ^$ Any letter ( in the Find what box only) ^c Microsoft Windows Clipboard contents ( in the Replace with box only) ^& Contents of the Find what box ( in the Replace with box only) I am not satisfied, how Balabolka extracts text from PDF files. Can I use the other way for processing of PDF? The process of text extracting from PDF files is complicated enough, because PDF files do not contain plain text. You may use an external command-line utility for text extracting: for example, the program pdftotext.exe from the project.
